SPECIFICATION forming part of Letters Patent No. 404,224, dated May 28, 1889. Application filed February 16, 1889. Serial No. 300,140. (No model.)

To all whom it may concern:

Be itknown that 1, CHARLES Esrns REcroR, a citizen of the United States, residing at J ersey Oity, Hudson county, in the State of New Jersey, have invented new and useful Improvements in \Vindew-Ventilators, of which the following is a specification.

My invention relates to that classof window-ventilatorswhich may be inserted in any window and removed therefrom. It is designed to prevent the entrance of dust, while it allows of the introduction of air, which is directed upward and away from any person sitting next the window. It is provided with means for regulating the inflow of air, and is especially adapted to car-windows.

My ventilator consists of a panel, the bottom of which rests against the sill of the window, while its two sides are held against the window-jambs. The panel is provided with two feet, which project laterally on each side of the base, and which fit to and extend across the sill under the window-sash, and the ventilator is held in place by the closing down of the sash against the feet. The height of the feet is sufficient to allow of a free circulation of air under the closed window-sash into the space between the panel on the inside of the sash. The top of the panel has a cover closing over the space between the sash and it, with an adjustable valve for the admission of the air. A wire or other grating extends between the top of the ventilator-feet and the panel, and another grating extends across the opening of the valve.

In the accompanying drawings,which illustrate my invention as applied to a double car-window, Figure 1 is a view in perspective of the inside of a window with the ventilator applied. Fig. 2 is a View, also in perspective, of the ventilator. Fig. 3 is a view in crosssect-ion of the window and ventilator; and Fig.

' 4, a view on the line 00 0c of Fig. 3, looking down, and showing the top of the Ventilator.

A B are the window-jambs.

O is the sill.

D E are the sashes of the interior and exterior windows.

F is the ventilator-panel resting upon the sill O and the jambs A B.

G H are the feet secured to the base of the panel, fitted to and extending across the sill C.

I is the grating which closes the space between the panel F and sashes E D.

J is the hinged cover, having the aperture K, closed by the valve L, sliding in guides M M.

N is the grating across aperture K.

O is a tubular weather-strip fitting into a groove, P, in the base of panel F, so as to make an air-tight joint between it and the sill O.

Q is a groove in cover J into which, when closed, fits a corresponding projection, R, on the top of the panel, in order to form a tight joint extending the entirelength of the cover.

S and T are handles by means of which the ventilator is raised, and with it the windowsash, so that the ventilator may be withdrawn.

The operation of the ventilator is as follows: The sashes A B-having been raised, the ventilator is inserted into the window with its feet G H extending across the sill and under the sashes. The latter are then closed down against the feet, and the ventilator is thus held in place. The hinged-cover J being also closed, the air enters between sashes D E and sill O, and, abutting against panel F, is directed upward between the panel and the interior sash, E, being first purified by passing through the grating I, and then passes out of the ventilator through grating N in aperture K, the quantity being regulated by means of valve L.

I have shown my ventilator as applied to a car having double windows; but it can readily be adapted to the windows of other vehicles or of a house withoutv departing from the spirit of my invention, and is equally operative with a single or double window. I have alsoshown the panel F as resting against the jambs of the window; but it may, if desired, be made to fit between the j ambs, so as to present a surface flush with the j ambs and wall.

The panel may be of wood, or may contain a mirror or a transparent sheet of glass to correspond with the interior decorations of the apartment, as shown in Fig. 3.

It is obvious that I may dispense with the grating I and purify the air by its passage through grating N, or, vice versa, may dispense with the cover J and rely solely upon the grating N.

It is thus seen that my invention consists,

ICO

essentially, of a ventilator of two sides connected together at right angles to each other in the shape of a capital L, the vertical limb of which is a solid panel, while the horizon tal limb against which the window-sash closes is partly removed for the admission of the air into the space between the vertical limb and the window-pane.

The advantages arising from the use of my improved ventilator consist in the great simplicity of its construction and the absence of any projection into the interior of the apartment; the facility with which itmay be insertcd and removed; the complete protection from any draft of the persons in its neighborhood, while at the same time a plentiful supply of fresh air, purified from all dust or smoke, is readily admitted into the apartment, and the accessibility of its inclosed spaces by means of the cover, so that any article accid entally dropped between the ventilators and the sash can be easily recovered.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A window-ventilator consisting of the vertical side or panel F, extending, when the ventilator is in place, up and in front of the window-pane, so as to leave an air-passage between it and the pane, and the second perforated side at right angles thereto, consistin g of the laterally-proj ectin g feet G .ll,whereby the ventilator is held in place by the closing down of the window-sash, and the grating I, whereby the air is admitted and purified, substz'tntially as hereinbefore set forth.

2. The combination, with a window-ventilator consisting of the vertical side or panel F,

extemling,when the ventilator is in place,up

and in front of the window-pane, so as to leave an air-passage between it and the pane, and the second side at right angles thereto, eonsisting of the laterally-projeeting feet G H, adapted to fit over the window-sill and under the sash, of the cover J, having the aperture K, grating N, and valve L, substantially as and for the purpose set forth.

3. The combination, with a Wlll(l0\ -ventilator consisting of the vertical side or panel 1', extending, when the ventilator is in place, up and .in front of the window-pane, so as to leave an air-passage between it and the pane, and the second perforated side at right angles thereto, consisting of the laterally-projecting feet G 11, adapted to fit over the window-sill and under the sash, and the grating I, of the hinged cover J, having the aperture K, grating 1T, and valve L, substantially as and for the purpose set forth.

4. The combination, with a window-ventilator consisting of the vertical side or panel 1 extending, when the ventilator is in place, up and in front of the window-pane, so as to leave an air-passage between it and the pane, and the second side at right angles thereto, consisting of the laterally-projecting feet G II, adapted to .fit over the window-sill. and under the sash, of the hinged cover J, havingthe aperture K, grating N, valve Ti, groove Q, and projection I, substantially as and for the purpose hereinbefore set forth.

I11 testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
